How to parse an HTML-like file??
-
hello, I need to parse a text file and take some tag as or , I need it to be written in C, do you think I better use an XML parser ( if yes, which one should I use?, I premitt that I've not got much experience with XML) or should I better so it sequentially by doing
if( strcmp(line,"<cover..............)???thanks in advance Paolo -

Use a state machine, switching states when you reach a '<' or a '>', adding the finished tags or between-tag-content to arrays as appropriate. As a matter of a fact, you should have state changes for spaces and '='s inside the tags as well.

<img, it'll call your callback, notifying you of that. Then when it findshref="img", it'll call your callback notifying you of that. So, basically you need two (possibly three) callbacks. One for notifying you that you've<imghas begun, one that tells youhref="img"was found, and possibly one that says</img>. Here's one such parser: libxml2[^]. It's licensed under the MIT License, so there's no problem using it in a closed source/commercial application. -- Ich bin Joachim von Hassel, und ich bin Pilot der Bundeswehr.
